Abstract
An extensive study of the secondary metabolites produced by the marine sponge Smenospongia cerebriformis has led to the isolation of two new bisspiroimidazolidinone derivatives, dictazolines A (1) and B (2), along with the known soft coral metabolites tubastrindoles A (3) and B (4). The structures were assigned by 2D NMR spectroscopic methods.
